Asp page cannot be displayed normally in IIS

I suddenly found that the asp page could not be displayed normally in IIS. I canceled the "show friendly http Error" in ie and found the following information:

Server Application Error

The server has encountered an error while loading an application during the processing of your request. Please refer to the event log for more detail information. Please contact the server administrator for maintenance.

In addition to a lot of explanations, I will not explain the solution here. The procedure is as follows:
1. Change the password of the IWAM_Myserver account, which is assumed to be "000000 ".
2. Modify the password of the IIS IWAM_Myserver account. In the c: \ inetpub \ adminscripts \ directory (the default directory for IIS installation), enter:
Cscript adsutil. vbs set w3svc/wamuserpass "000000"
("0" indicates the User-Defined password)
After the modification is successful, the system prompts as follows:
Wamuserpass: (string )"******"
3. For the IWAM_Myserver password used to synchronize com + applications, enter:
Cscript synciwam. vbs-v

If there is no error message, OK.
